Somewhere in the depths of the Pacific Ocean…
Captain Nemo stands by a large wooden crate in the center of the cargo hull of the Nautilus. "By thunder!" he mumbles for himself, "he did it!" He circles the crate once more, with a satisfied grin. Then pulls a telegraph paper from his pocket :

"Dear Captain Nemo,

The solution to the problem we discussed on the Nautilus deck is finally in your hands. I hope the assembly of this rather funny contraption did not cause concerns. As you requested, I built an alternative source - therefore, when Nautilus is on the surface, the engine will use fossil fuels. When submerged, the engine will lend a negligible amount of electricity from your ship's batteries.

Until we meet again,
Your friend,

Nikola Tesla"
